4iiii PRECISION Power Meter For Shimano XTR M9000

Compatibility

Crankset: The 4iiii power meter is compatible with XTR M9000/9020/9030 cranksets. It is also compatible with all other Shimano x000/x020/x030 series MTB cranksets such as the XT M8000/M8020/M8030 or the SLX M7000/7020/7030.

It is not compatible with the newer x100 series cranks such as the XTR M9100, XT M8100 or SLX M7100.

Check Frame Clearance: Crank-arm based power meters like this one attach a sensor on the inside of the left crank arm. On some bikes, there is not enough room between the left crank arm and the chainstay for the sensor to clear the frame. Therefore, you should make sure you have at least 10 mm of clearance between the left crank arm and the chainstay - and that you don't have a bottom bracket mounted rear brake (used on some aero and TT bikes). The important area to measure is right in the middle of the crank arm. Please refer to the image below.

If you find that you have around 7-9 mm of clearance, what many people will do is simply install a 1 or 2 mm bottom bracket spacer (between the left crank arm and the frame), which will give them the clearance they need.

Common Questions and Answers

Question: How do I determine what length my current cranks are so I can make sure I get the same size?

• Your crank arm length should be printed or stamped on the inside of the left crank arm, usually near the pedal end.
